Sorry Bill but if you have to ask why an appliance is tripping out a fuse that means you have no idea about electricity or the danger involved in playing around trying to fix it.. Anyone who gives you advice and suggests you try things yourself is in my opinion being irresponsible & putting your life at risk. My advice is that there is something seriously wrong with the electrics in the machine and you should get an expert in to fix it properly for you.
